Use a CAGradientLayer:

let gradientLayer = CAGradientLayer()
gradientLayer.frame = CGRect(x: 0, y: view.frame.size.height - 1, width: view.frame.size.width, height: 1)
gradientLayer.colors = [
    UIColor.white.withAlphaComponent(0.5).cgColor,
    UIColor.white.withAlphaComponent(0.0).cgColor
]
view.layer.addSublayer(gradientLayer)

Adjust the gradients colors to you needs.
